Title: Improvements in stainless steel clad with aluminum
IPC: B23K20/227
Filed: 1965-05-04
Abstract: 1,057,523. Making compound sheets; rolling. REVERE COPPER & BRASS Inc. May 4, 1965 [May 14, 1964]. No. 18701/65. Headings B3A, B3M and B3V. In a process for bonding aluminium to stainless steel, sheets of these metals are placed into contact without removing the normal oxide coating from the aluminium, the sheets are hot worked at a temperature of 700‹ to 1050‹ F. to compress the sheets causing plastic flow of the aluminium which becomes adhesively bonded to the stainless steel, the sheets are then cold worked, causing the metal to elongate by at least 5% partially breaking down the oxide film and the bond between the two metals and exposing areas of nascent metal at the interface which becomes metallurgically bonded when the sheet is heated to at least 500‹ F. Prefer ably pure aluminium or aluminium alloy containing not more than 3% alloying constituents is used. The hot working may be performed by rolling causing an elongation of 2 to 4% in the stainless steel and 20 to 35% in the aluminium, the difference in speed of the metals passing through the rolls being allowed for by using different roll speeds, or different finishes on the rolls in contact with the two metals. The cold working operation may be carried out by means of rolling, or by drawing such as in the manufacture of saucepans. The purpose of the final heat treatment is to cause diffusion of the nascent metal brought into contact by the cold rolling, thus increasing the strength of the bond. Any conventional stainless steel, may be used in the process. The material may be used in the production of cooking utensils or reaction vessels.

Abstract: 452,948. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. July 1, 1935, No. 18817. Convention date, June 30, 1934. [Class 38 (iii)] Non - regenerative braking ; varying E.M.F. -A locomotive motor is supplied during normal running from an alternating current source through a transformer t and a grid -controlled rectifier, and during rheostatic braking, when its armature a is connected to a resistance r, its series field f is separately excited from the grid-controlled rectifier through which the motor is supplied during the running operation. The braking is regulated by grid control of the rectifier, the resistance r being constant. The voltage for the separate excitation of the field is suitably reduced by making connection to low-voltage tappings on the rectifier transformer t or by operating a switch u to establish a suitable fresh neutral point on the transformer winding. Sudden field changes may be avoided by connecting a choke d in the field circuit, and, if necessary, shunting the field by capacity-inductance circuits. The field circuit may include a stabilizing resistance carrying the armature current.
Patent GB-407359-A (GB)
Title: Improvements in the manufacture of artificial filaments and the like
IPC: D06M13/08
Filed: 1932-07-04
Abstract: To reduce the tendency to creasing shown by artificial filaments, threads, ribbons, &c. which have been stretched during their manufacture or subsequently thereto, the materials are treated with a solvent or softening agent under such conditions that only the outer layers of the filaments &c. are acted upon or softened or rendered plastic.  The treatment serves superficially to destroy the parallelization of the micelles.  The restriction of the action to the outer layers may be achieved by applying the solvent in small quantities as for example diluted or in the vapour state, or by permitting the agent to act for a short time only.  The properties of the solvent and its conditions of application must be such that shrinkage of the materials would not take place, in particular, volatile solvents such as methylene chloride are not suitable.  When a diluted solvent is employed, the action of the solvent may be hastened by evaporation of the diluent, this being chosen to be more volatile than the solvent. The localizing of the effect of the solvent may be secured by heating the filaments carrying a limited amount of the solvent as by passage over heated drums &c. or through a bath of heated liquid.  If during the removal of the solvent, its concentration decreases, a dull product may result; on the other hand, if the concentration remains the same or increases, the lustre will be maintained or even increased.  A slight stretch may be applied to the materials during treatment.  The latter may be carried out on the materials in packages or while travelling, and it may be separate from or continuous with the original stretching operation. In examples, cellulose acetate yarns containing one denier filaments are treated for 30 secs. with aqueous methylated spirit, for 2 mins. with tetrachlorethane-toluene, for 30 secs. with 10 per cent glycol monoacetate, and for 15 mins. with turkey red oil at 80 DEG  C., and are passed at 20 metres per min. over a heated roller running in diethylene glycol at 105 DEG  C.

Abstract: 715,957. Aerials. GENERAL ELECTRIC CO., Ltd., and KING, D. LA W. W. Nov. 10, 1952 [Aug. 10, 1951], No. 18921/51. [Class 40 (7) An aerial system comprising an open-ended waveguide 5 is provided with a plurality of spaced parts 6 and 7 which project into the guide from the walls and serve to modify the radiation patterns. The arrangement is of particular application with circularly polarized radiation which may be considered as two component plane-polarized waves having their electric vectors in the X- and Y-planes respectively. In the case of the component with the vector. in the X-plane, the guide is effectively bounded by,.walls 8 and lines 12, and by correctly choosing the distance parts 7 project into the guide, the resulting X- and Y-plane polar diagrams may be made substantially the same. Similarly, for the component having the electric vector in the Y-plane, the guide is effectively bounded by walls 9 and lines 11, and if the parts 6 have the same dimensions as parts 7, the two polar diagrams are the same as those due, to the other component. By this means the resulting radiation remains substantially circularly polarized at all points in space contained in a wide solid angle Reference is made generally to elliptically polarized, waves, and also to the use of two in-phase waves having their electric vectors parallel to walls 8 and 9 respectively. In this latter case the resulting radiation is plane polarized at an angle which is set by the relative amplitude of the two waves. A circular waveguide may be used with the parts projecting radially into the guide. The parts are made about one wave-length long, although parts 6 and 7 need not be of the same length, and taper as shown at 13 to prevent any impedance discontinuity. The front ends terminate flush with or just short of the open end 10. The parts may be inclined to the guide walls. The corners of the tube forming the guide may be rounded off since the corner parts are not used in propagation. A thin window may close the open end or, alternatively, the guide may be filled wholly or in part with a solid or foamed dielectric. The waveguide walls and parts may be made of a dielectric material.
